ssh login with publickey still ask password - ssh

Question

I have add public key id_rsa.pub to remote /home/user authorizationkeys. About permission this file was 600 and parent dir .ssh was 700. I have also modified sshd_config.
when I perform ssh -vv user#remote errors show below
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug2: key: /home/hjjj/.ssh/identity ((nil))
debug2: key: /home/hjjj/.ssh/id_rsa (0x55b3d8c54bc0)

Thanks first. I checked below: I haved login client with non-root userA and I want to login remote server with non-root userB which I can access successfully with password authentication. I also add userA's id_rsa.pub to userB's authorized_keys file. The sshd_config was---
# Authentication:
#LoginGraceTime 2m
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
#AuthorizedKeysCommand none
#AuthorizedKeysCommandRunAs nobody
And I can't find auth.log under /var/log but /var/log/secure. After I execute ssh userB#remote -p 9998 on client, the log output was:
sshd[22208]: Connection closed by 192.168.5.38

When you have problems with ssh, it's always a good idea to start ssh with -v.
From your log you can see that you offered your key (Offering public key: /home/hjjj/.ssh/id_rsa),
but it wasn't accepted (missing Server accepts key)
The next steps on the client side should be:
Verify you are using the correct user
Verify that you are connecting to the expected server
Then you should switch to the server:
Check your /etc/ssh/sshd_config for PubkeyAuthentication yes
Check the entries in /var/log/auth.log
